Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed May 2,1905. Serial No. 258,512.

To aZl whom it may concern:

Be it known that I, HENRYARNESON, a citizen of the United States,residing at Ruthton,

' in the county of Pipestone and State of Minnesota, have inventedcertain new and useful Improvements in Chain Belts; andI do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

My invention relates to improvements in chain belts; and the object isto provide a chain belt the links of which cannot come accidentallyapart when getting worn and which are unusually strong for being made onthe principle that the links hook into each other and are not slippedtogether edgewise. This object I attain by the novel construction andarrangement illustrated in the accompanying drawings, in which Figure 1is a plan view of two links of my chain belt joined together. Fig. 2 isan edge view of one link and a portion of another, the latter beingrepresented in two positions by dotted lines. Fig. 3 is a portion of alink of the chain, showing the effect of wear upon it.

Referring to the drawings by letters of reference, the links are allalike and are preferably or' a rectangular form, composed of side barsA, which may be approximately cylindrical, and are connected by acylindrical crossbar B and a hook-bar C, having a hook D serving as ajournal for the bar B of the next link.

In the rear corners of the link, where the link is strongest to standit, are provided two notches E, which receive the guards F of the frontcorners of the next link while the latter is folded from the position Ato the position A in Fig. 2, thus rolling the bar B into the hook D, inwhich it may turn till the link occupies the position A or as far as itwill ever be swung in ordinary use. The bar B is thus held in place bythe hook D and the guards F until it is desired to detach the links,when the bar B is rolled out by swinging the link, as from A to A. When,however, the bar B has become old and worn, as shown on the inner sidein Fig. 3, it is apt to become dis engaged from the book when the chainis slack and the link approaches upward to the position A To preventsuch annoying accidental separation of the links, I provide in bothsides of the hook D recesses Gr, which relieve the bar B from wear nearthe ends, so that it will always have remaining round portions H toprevent its exit from the hook until the link is brought into theposition A or still further folded toward the next link, which is onlydone with intention to get them apart.

From the above description it will be understood that I provide a chainbelt of links whose bar B is not weakened by any grooves or notches inits main body, where the most strength is required, but has thenecessary notches E in the ends forming the corners of the link, whichcan well stand it, as they are of greater cross-section than any of thebars of the link. It will also be seen that by means of the recesses G agreat advantage is gained in the construction and durability of suchchains.

Having thus described the invention, what I claim, and desire to secureby LettersPatent, is

1. A chain-belt link having the recesses G in the sides of itscoupling-hook to prevent the entire bar working in the hook from wearingout of cylindrical shape and thus permitting separation of the links.

2. A chain-belt link comprising the side bars A having the guards F atone end of the link, the round end bar or cross-bar B with the endnotches E, the cross-bar C with the hook D having the recesses Gr,substantially as shown and described.

In testimony whereof I afiix my signature in presence of two witnesses.

I HENRY ARNESON.
